The OPA2277U/2K5G4 is a high-precision operational amplifier from Quarktwin Technology Ltd. It features an ultralow offset voltage of 10 OºV and an ultralow drift of ¬±0.1 OºV/¬8C, making it suitable for applications requiring high accuracy. The amplifier offers a high open-loop gain of 134 dB and excellent common-mode rejection of 140 dB, along with a power supply rejection ratio of 130 dB. With a low bias current of 1 nA maximum and a wide supply range from ¬±2 V to ¬±18 V, it is versatile for various applications. The OPA2277U/2K5G4 is designed for use in transducer amplifiers, bridge amplifiers, temperature measurements, and strain gauge amplifiers. It operates with low quiescent current of 800 OºA per amplifier and is available in an 8-pin SOIC package. The device is stable in unity gain and provides excellent dynamic behavior across a wide range of load conditions. It is a suitable replacement for industry-standard amplifiers such as the OP-07, OP-77, and OP-177, offering improved performance characteristics.
